1. You are interested in testing the effects of levofloxacin on Burkholderia cepacia. Based on what you have learned using Labster, design a simple experiment by which you could test the effectiveness of this antibiotic on killing this bacterium.

A scientist wants to make a solution of tribasic sodium phosphate, Na3PO4, for a laboratory experiment. How many grams of Na3PO4 will be needed to produce 500. mL of a solution that has a concentration of Na+ ions of 0.700 M ?

Microbiology actually:
Agglutination test

what type of antigen is detected in each reaction (A, B, C, D, F and G)?

In this experiment latex particles are covered with IgG specific to Strep antigen. what is the purpose of this?

Lead lime can be converted into lead when heated in a hydrogen atmosphere.

- Write down a modern reaction scheme.

- Suggest a way to carry out the experiment that clearly reveals that water is formed during the reaction.

a heat transfer experiment consist of a stream of air blowing over a heated horizontal plate. what causes the formation of both velocity and thermal boundary layers? what causes a difference in thickness between them?

An experiment is given together with an event. Find the (modeled) probability of each event, assuming that the coins are distinguishable and fair and that what is observed are the faces uppermost.

Four coins are tossed; the result is more heads than tails.

In an experiment the sample mean of a set of measurement is 10 mm and the sample standard deviation is 4 mm for a sample size of 36. Using sketch indicate where we can expect the location of population mean

An experiment consists of repeatedly tossing 2 fair coins until the toss results in one each of a Head and a Tail. What is the mathematical expectation of the number of times you will need to toss the 3 coins to achieve this?

Suppose an experiment is performed in which a plant is supplied with normal carbon dioxide but with water containing radioactive oxygen atoms (O¹⁸). At the end of photosynthesis where would the O¹⁸ atoms be/end up/go? Explain.

Question about a thermoelectric cooler (TEC)

Why is it expected that one side has a greater difference from room temperature to the other?

In my experiment, there was a larger difference between the room and the cold block

Thanks
